BLUE THUMB PUMP INFORMATION
Blue umb products are created by experienced pond professionals. ese multi-purpose submersible
pumps are designed for use in water garden and koi pond ltration systems, and to create waterfalls, streams
and water features.
Mag-Drive models are suitable for pumping clear ltered water, such as when using a Blue umb
Pond Skimmer or when placed inside a pump sock. e temperature of the water being pumped must
never exceed 95 degrees Fahrenheit. Do not pump sewage, inammable, corrosive or explosive liquids

For Your Safety

Installing the pump
